Some so-called “composting” toilets and outhouses still mix pee and poop — actually creating illegal sewage.
THAT'S NOT COMPOST..
That’s blackwater — a toxic slurry of E. coli, salmonella, giardia, and parasites. It pollutes land, leaks into oceans, and poisons groundwater.
IT'S COMPLETE MADNESS
Mixing urine and feces into fresh water creates a harmful concoction capable of killing us all.
“Most people don’t realize this: when you mix pee and poop, you create sewage. By separating them, you eliminate sewage production and the need for septic systems or waste handling facilities. You can turn waste into fuel. It’s magic. And it’s science.” —Eric M., Eco Toilets Founder

Eco Toilets Maui are handcrafted using insect and mold-resistant materials — built to last in island life. Each one is off-grid, solar-powered, and beautiful enough to live inside your home. Like fine modern furniture, not a porcelain piss pot.

Flush toilets mix pee, poop, and clean water into a toxic witches’ brew. That’s not sanitation — that’s pollution.

☀️ It’s run by the sun — clean, free energy
🌿 No smell. No pipes. No sewage

Eco Toilets Maui are clean, legal, land-friendly systems designed for island life. We separate waste at the source — no smell, no sludge, no lies. Built by hand on Maui and powered by the sun, they’re the future of waste in Hawaiʻi.

WHY are we flushing that "GOLD" humanure away…
…and buying imported “dirt” that brings invasive bugs and chemicals?
HOW much are we spending to fight the coconut beetle —
while we’re still importing the same kind of soil that brought it here?
WHY are we threatening native plants and ecosystems —
when we could be regenerating from within?
WHY are we flushing sacred drinking water,
especially when toilets use 20%+ of household supply —
and so many of us live on rain catchment?
WHY are we still relying on septic tanks, cesspools, and leach fields —
systems that leak, stink, and poison our ocean and ʻāina?

We’ve been treating a natural resource like trash.
Most systems mix urine and feces, creating toxic sludge that breeds parasites, releases ammonia gas, and contaminates groundwater with methane and pathogens. It’s not just gross — it’s dangerous.
And most so-called “composting toilets”? They’re not composting. They’re making raw sewage — illegal without proper waste handling infrastructure.
Eric knew there had to be a better way. So he built it.
Eric knew there had to be a better way. So he built it.
Eco Toilets Maui is based on one simple truth: separation is transformation.
Just like your body separates streams, our systems do the same — turning “waste” into value: Urine is diverted to nourish plants or filter into greywater systems. Feces becomes safe, legal compost or clean-burning biogas — capable of powering a stove, water heater, or generator.
This work is a blend of Eric’s lived experience, engineering brilliance, and deep Aloha for the land.
Each Eco Toilet is handcrafted at our Pauwela Studio in upcountry Maui using mold-resistant, pest-proof materials — made for island life.
The system is clean. Legal. Sustainable. Built with care by people who truly give a sh*t.

Biogas Is Nature’s Way of Saying Nothing Is Wasted
Biogas Is Nature’s Way of Saying Nothing Is Wasted
The same anaerobic digestion process that starts in your stomach continues in a biodigester — breaking down organic waste and releasing methane, one of the cleanest-burning fuels on Earth.

How It Works
Eco Toilets Maui builds custom biodigesters for homes, farms, and communities. Once your system is set up, it captures methane from decomposing humanure and compresses it into CNG (Compressed Natural Gas) using a simple pump and filter.

Your kitchen cookstove
A water heater
A backup generator

The Result?
Clean, safe methane — hotter and cleaner than propane or fossil fuels.
Zero sewage. Zero runoff. Zero carbon footprint.
